KELLY, '01 :DETHOIT, MICHIGAN, .ASSIGNOR TO DETROTT STEEL PRODUCTS COJ'BIEAN'Y, DETROIT, MICHIGAN, A CORPORATION OF IiIICHIGAN THRESHOLD CONSTRUCTION Application filed September 29, 1930. Serial No. 485,222.

The invention relates to threshold constructions and refers more particularly to threshold constructions for swinging closures. One of the objects 01 the invention is to soform the threshold construction that it is adapted to be used with closures which open-by swinging either inwardly or outwardly. Other objects are to so form the threshold construc tion that it cooperates with the closure to prevent passage therebetween of'wind, water or the like; that the Weatherstrip, element between the threshold element and the closure is carried by the former and forms an abutment for the latter and that the weatherstrip element is readily replaceable and does not interfere with stepping on or over the threshold construction A further object is to so construct the threshold element that it has means for positioning the clamp which secures the Weatherstrip element in place and for positioning-a frame at one side of the closure. I

These and other objects of the invention will become apparent from the following descriptiontaken in connection with the accompanying drawings in which Figure 1 is a perspective View illustrating a threshold construction embodying my invention; I,

Figures 2 and 3 are vertical sections there- I through;

Figures 4;, 5 and 6 are views similar to Figure 2 showing modifications. The threshold construction is designated by the reference numeral 1 and the closure by the reference numeral 2. This closure may be a door or a window and, as shown in t e present instance, is a casement door of metallic construction having the side rails 3 and the bottom rail 4 of like cross section.

The threshold construction comprises the metallic threshold element 5 which is preferably formed of brass. 'This threshold element is of inverted channel shape and has in terniediate i s side legs the horizontal raised portion 6 at one edge of which are the spaced upright projections 7 extending longitudinally of the threshold element and providing spaced shoulders, which with the portion of the threshold element between the projecupwardly. portion 6 there is the vertically extending tions form the groove Swhich extends longitudinally of the threshold element and opens At the other edge of the raised shoulder 9 which is connected to the adjacent side leg by the inclined portion 10. The projections 7 are connected into the other side leg by the inclined portion 11, which is formed with the spaced grooves 12 extending longitudinally of the threshold element. For reinforcing the threshold element there is the longitudinally extending leg 13 located below the portion of the threshold element having the projections 7. The bottom rail 4 of the closure has the'clepending flange l, which in the closed position of the closure extends adjacent the shoulder 9 of the threshold element.

14 is the Weatherstrip element which, as shown in Figures 1 and 2 particularly, is formed'oi felt. This Weatherstrip element is clamped upon the raised portion 6 of the threshold element and extends outwardly beyond the shoulder 9 to engage and form an abutment for the depending flange 4: of the closure to prevent the passage of wind, water or the like between the threshold construction and the closure. For securing the weathers-trip element in place and at the same time protecting the same, I have provided the metallic cap 15 having at one edge the leg or flange 16 which enters the groove 8 and is thereby positioned upon the threshold element. This cap rests upon and is clamped against the Weatherstrip element by suitable means such as the screws 17, which are threaded into the raised portion 6.

lVith this arrangement the Weatherstrip element'is protected and does not interfere with stepping on or over the threshold construction. Also it forms an efiective seal between the closure and the threshold construction and a yieldable abutment for the closure to eliminate at least in part and noise incident to moving the closure to closed position.

As shown particularly in Figures 1 and 3, a window frame is located at one side of the casement door frame 18 and secured to the threshold element 5. This window frame is of metallic construction and has side and bottom rails 19 and 20, respectively, of like cross section. This window frame is positioned upon the threshold element by engagement of the leg 1 of the bottom rail in the groove 80f the threshold element, the other leg 22 overlapping the shoulder 9. The window frame is secured to the threshold element by suitable means such as the screws 23. it will thus beseen that the groove 8, in addie ,tion to positioning the cap for clamping the Weatherstrip element in place, positions the window frame and that the reinforcingleg of the threshold element serves to-reinforce the same and to carry the load of the window, as well'as thatincident .to stepping.-.

upon the threshold construction. I

' In the modificationshownin'Figure' 5t, the easement closure opens inwardly instead l of outwardly, as shown in Figures 1, 2 and 3, and thethreshold construction is reversed toadapt the same to this typ e'of closure. This closure is also a casement door of me tallic construction and is glazed on the out side and to assist in ,weatherpro'ofing there i's'the' metallic Weatherstrip element 24 which is secured upon the bottom rail of' thedoor outside the glassand has the downwardly and outwardly inclined? flange 25 terminat- 'ing a substantial distance outwardly from the spacebetween the bottom .rail and the threshold construction. 7

Z'In the modification shown in F igure 5, the

same. general arrangement of parts is prescut, with theexception that the Weatherstrip element 26 is clamped in place by an integral part 27 "of the threshold element-I This eatherstrip element is inserted into place when the part 27 occupies the position shown by thedotted lines and after having been inserted into place the part 274is pressed down to tightly engagethe Weatherstrip: element." f I x li -lgure 6 discloses another modification in which the Weatherstrip element 28 is formed of spring metal, such as spring bronze, and

it secured place by means of the cap 29,-wh1ch inturn is secured to the raised portion'o-f the threshold element by means of the screws 30. What I claim as my invention is:

A' threshold construction fora swinging closure provided with a depending flange, which comprises a threshold element having a shoulder adjacent which the depending vflange extendsin the closed position of the closure, and a Weatherstrip element secured to said threshold element-and extending'beyond said shoulder and forming an abutment for the depending flange. 7 e
